Study on low-pressure flare gas recovery process scheme of in-service offshore oil platform
Offshore oil and gas resources have become an important part of China's oil and gas resources.In the production process of offshore oil and gas,most of the low-pressure as-sociated gas is flared and then vented,which not only causes a waste of resources,but also does not meet the requirements of energy saving and carbon reduction.Taking the flare sys-tem of offshore oil platform in Bohai oilfield as an example,this paper analyzed the flare gas recovery process scheme of offshore oilfield,combined with the characteristics of flare gas recovery of offshore oilfield,and proposed the flare gas recovery process scheme of"pressure control valve+quick opening valve+buckling pin valve+liquid ring compressor",and adopted the plasma immediate ignition flare to replace the existing traditional flare on the platform.The recovery of low-pressure flare gas on the platform is realized,and the safe and stable operation of the flare system is ensured.This scheme can provide reference for other oil and gasfield flare gas recovery,and has important significance for realizing green and low-carbon development of offshore oil and gas.
